As Wilkbez-seen byreference toy Figure'2; the rst shackle Msuponuengaging worm-Wheel 3l, willsquicklyrpass:beyond` short arm 9-of rocker 'l and thereupon engage long arm Il. The Weight of the carcass suspended from the shackle passing through the feeding mechanism will cause hook 138 to depress long arm l l within slot 2, thereby raising short arm 9 above the surface of bleeding rail l. Short arm 9, upon being raised, will serve to stop the next succeeding shackle 4S and continue in that position until the preceding shackle has cleared arm Il.I Arm Il, upon being cleared, will resume its normal position by action of coil spring 2l, thereby loW- ering short arm il to permit passage of the next succeeding shackle in contact with Worm wheel 3l. l

It is apparent from the foregoing description that shackled carcasses traveling on bleeding rail l may be spaced at any suitable distance by changing the gearing of worm Wheel 3l or by altering the length of long arm El of rocker 'I to relatively alter the action of short arm 9.

At discharge end 33 the carcass will be released from its respective shackle by releasing-meansy 53 and the shackle returned to the shackling pen on a shackle return rail provided therefor,-`

In a conveying means including an inclined rail for the gravity conveyance of objects thereover and having a recess in the surface thereof, means for spacing the objects advanced on the conveying means comprising a rocker lever pivotally mounted within the recess and normally adapted for the passage of the objects traveling onthe rail, and a Worm wheel rotatably mounted in operative relation With the rocker lever for controlling the advance of the objects relative t the rocker lever.-

8. In a conveying means including an inclined rail for the gravity conveyance of objects thereon and having a recess in the surface thereof, means forspacing the objects advanced on the conveying means comprising a spring-tensioned rocker lever pivotally mounted within the recess and normally adapted for the passage of the objects traveling on the rail, and a worm Wheel rotatably mounted in operative relation with the rocker lever for controlling the advance of the objects relative to the rocker lever. l

9. In a conveying means including an inclined rail for the gravity conveyance of object supporting shackles and having an elongated slot, means for spacing the shackles on the rail comprising a rocker lever pivotally mounted within the slot and normally adapted for passage of the shackles traveling on the rail, and a worm wheel operatively mounted relative to the rocker lever for controlling the advance of the shackles relative to the rocker lever, the rocker lever being operable for withholding succeeding shackles during passage of a shackle thereover.

l0. In a conveying means including an inclined 5 rail for the gravity conveyance of object supporting shackles and having an elongated slot, means for spacing the shackles on the rail comprising a rocker lever pivotally mounted Within the slot and provided with arms adapted for pivotal move- 10 ment above and below the surface of the rail, the arms being normally adapted for passage of the shackles traveling on the rail, and a worm Wheel rotatably mounted in operative relation with the rocker lever for controlling the advance 15 of the shackles traveling relative to the rocker lever, one arm of the rocker lever being operable for withholding succeeding shackles during passage of a shackle over the other arm of the rocker lever. 20 11. In a conveying means including an inclined rail for conveyance of object supporting shackles and having an elongated slot in the upper surface thereof, means for spacing the shackles traveling on the rail comprising a rocker lever pivotally mounted within the slot, the rocker lever having a long arm and a short arm respectively extending with and against the path of travel of the shackles on the rail and adapted for pivotal movement above and below the surface of the rail, the arms being normally adapted for passage of the shackles traveling on the rail, and a worm Wheel rotatably mounted in operative relation with the rocker lever for controlling the advance of the shackles relative to the rocker lever, the arm extending against the path of travel of the shackles on the rail being operable for Withholding succeeding shackles during passage of a shackle relative to the arm extending with the path of travel of the shackles on the rail.
